How do I generate pulses from the block PWM Generator to operate the switches if they are more than four?

Hello every one
I hope to find any ideas for my inquire.
my question as in the picture there are two models, the left one five-level cascaded with PWM pulses to operate the switches, and the right one is a boost converter with a
PID controller to operate one switch. so here I want to use PI control to on five-level cascaded model but after PI block
How do I generate the pulses for 8 switches to operate them?

We have several methods:
  1. Simscape Electrical has PWM Generator(Multi-level) blk. : This generates multi-level PWM signals.
  2. You can refer to the 'Modular multi-level converter' at : Your left circuit is similar with MMC, so please visit above example.
  3. Additional comments : How about tie the switching devices with one blk. :
Hope this helps,

As answered on your other question by Joel. If none of the above workarounds help you, you will have to write your own algorithm to convert the scalar output into separate duty cycles.
